To all whom it may "concern:

Be it known that we, JOHN Emmsr B11.-

"Lmoron and CHARLES IIoLuwELL sii-jbjects 'ejoc-tc pushing themJzdge-on between two -adjacent.side of the l-inotype.

2-line letters thereon.

lhosc who are familiar withthe'machine production of li11'o ypes,-are aware that there ,is aceytain amount of tri'mmin -to be done to both" heir sides. This is chested by the parallel and vertical knives. A 2-line capital has its .lowerhalf projecting be end the Sue projec- "'tion, therefore, renders the trimming of'the sides of such a linotype by fi'xed knives impracticable, for the 'r ason' that the said passage would result in t is lower half or projection of the capital, or the lower halves or p'ojections of as many as th re may be, being shorn oil. Various mechanisms, some manual and some automatic, have been devised for longitudinally inovirg' the knife aplpertaining to the side of 'the linotype at w ich the 2-line lcttbr-overhangs,-out of tlie-way, sov that it may be clear of the overhang or overhangs, as many as there may be, and of returning the said knife to Its normal position ready for trimming ordinary .linotypes. In some of these-devices the presence of the projection has been relied on to stop the return mot-ion of the knife, in order that it should act only on as much of the linotype side as was-below the projection extending from it. In these last mentionedgleviccs, difficulty has been experienced owin r to the knife, in its return, sometimes ben ing the 2-line letter by which its sto )page is effected, and indeed in the case of tlnn Z-linc letters such as the capital I, the overhanging portion is sometimes shorn completely oil".

The object of the resent invention is to provide means for e acting the stoppage of the return movement of thelongitudinally adjustable knife by a special construction of 2 li-ne letter matrix composed into these-- sembled line of matrices.

In the accompanying drawings which are to be taken as part of this specification and read therewith ure 1 is an elevation of.

-is a sectional plan taken partly on the line 1515 of Fig. 13. According to this invention the lon itudinally movable knife 1 is moved in the neotion of its length, b any of the well-known means hitherto use for the purpose, for example by the spring-and-cam-actuated lever mechanism show in Figs. 3,3, 4 and 4, or, by a pin slidable in the first elevator as here inafter described with reference to Figs. 13 to 15 inclusive. This movable knife 1, at its upper end, is ifiigibly connected, as bymeans o a cord or equivalent 2, to a hor zontal slide 3 herein termed a feeler bar 111 ed 1n guides 4 on the vise frame 5, an through such cord to a weight or equivalent'fi, having a constant ten army to move thefeeler bar 3 towards the left of the machine that 1s The weight to say, towards the right-hand side of Fi 1, and therefore to raise the movable kn' e 1.

6, although not so shown, is preferably guided, say in a tube fast to the vise frame 5 so ing position when the vise frame is swung forward. The cord 2 is assed over suitable guide pulleys 7 rotatab y mounted on the vise frame 5, and is attached to the feeler bar 3 by a. pin or stud 9 carried by the said bar. The knife 1 is arranged to slide in uides in or on the knife block 10 and the fixe knife 11 is fast to the vise frame 5 both,. as in existing linotype machines.

Referring now to the knife operating mechanism shown in Figs. 3, 3, 4 an 4", it will be seen that the movable knife 1 is, at its lower end, connected by a link 13 to one end of a lever 14 whose 0 posite end is slidably fulcriyned (as by a s 011 shown in dotted lines in 3) on a pivot 15 fast to a bracket 16 known, in existing machines, as the starting handle bracket. At a point about midway of its length, the-lever 14 is pivoted to a lever 17 comprising two arms, one approximately horizontal to which the lever 14 is pivoted, and the other, an upstanding one,

aving pivoted in or on its free end, an anti-' friction roller 18 which, under the influence of the before described weight 6, has a constant tendency to remain 111 the .path of a rotating cam '19 which is fast to the ordinar cam shaft 8 of the machine. The lever 17 1s fulcrumed on a pivot 20 fast in a bracket 21 secured to the machine frame 22, and it is capable of transverse movement on the said pivot to such extent as to enable the roller 18 to be moved into and out of the operative plane of the cam 19. To impart this transverse motion to the'lever 17 there is provided a lever 23 pivoted to the bracket 21 and having on one of its arms two downwardly extending pins 24 one on either side of the horizontal arm of lever 17; the second arm of the lever 23 is connected to the rear end of a link or rod 25 whose front end' is suitably guided in a lu 26 fast to the starting handle bracket 16, an terminates in ahand or 100 27 situated at a position convenient to the and of the o erator.

In Fig. 4 the ro ler 18 is shown to be in the lane of operation of the cam 19, as it won d be when linotypes are being cast with 2-line letters thereon, and when it is desired to render the said cam non-effective and therefore retain the movable knife 1 in its uppermost position, as would be desirable when linot'ypes are required without 2-line letters thereon, the operator ulls the rod 25 towards the front of the mac ine, that is to say, towards the left of Figs. 3 to 4 and thereby moves the lever 17 towards the lefthand side of the machine, and the roller 18 out of the operative lane of the cam,19; the reverse of this 'a justment is effected that it will not fall from its workwhen the trimming devices, previously ad- {usted for trimmin etters, are to be a or trimming' linotypes having 2-line letters thereon. On the before-described feeler bar 3 is secured a feeler 28 which, in its leftward movement (under the influence of the weight 6) is adapted to engage with the right-most of the 2-line letter matr'ces 12 in the assembled'l'me, each of these matrices, according to the preserft invention, bein provided, for this purpose, with an extra ug or projection 29, see articularlyFigs. 9 and 10, extending from its foot in a downward and forward direction. The matrix shownin Figs. 9 and 1,0, is one suitable for forming a 2-line W such as is represented in Figs. 11 and 12, and, like all linot es with no 2-li,ne="-' justed f the other 2-line letter matrices, it' is adapted are assembled in the usual we for assem-' bling What are known as doub e-letter matrices', is, as heretofore, provided with a rib or ledge 33 which is either longitudinally adjustablc or, as shown in the accompanying drawi s, is fitted with an adjustable auxiliary le ge or portion 34, as described in the specification of Letters Patent No. 615909 so as to admit of the matrices being assembled with either the normal formative cavities or the variant formative cavities in the composing line. The ledges 33 and 34 may, as ordinarily, be moved into and out of their effective positions by levers 35, 36, respectively.

In addition to the adjustable ledges 33 and 34 in the assembler box 30, there is a third adjustable ledge 37 arranged below the auxdotted lines'in Figs. 6, 7 and 8, this spri serving to return the ledge 37 to its norm aflposition as soon as the lever 38, after previous operation, is released. The short ledge 37 as seen in Fig. 5, when in its normal or effective position, forms a continuation of the ordinary-ledge 40 on which rest the front bottom lugs of those matrices'which are assembled in: normal osition for casting printing faces of normal ont.

7 For temporarily securing the movable knife 1 in its adjusted position, there is provided a gripper 41, preferably pivoted to a bracket 42 fast to the vise frame 5 or to the knife slide 51 and to one end of which is socured a tension spring 43 whose other end is secured to the knife block 10 as shown in dotted lines in Fig. 2, this spring tending always to pull the upper end of the grip or 41 into its gripping position.

end of the gripper 41, there enga es the forward end of a horizontal push 10( 44 guidcd at said forward end in a lug 45 integral with thestarting handle bracket 16 and at its rearward end adjustably connected, as by the socket and nut 46, to a lever 47 pivoted at 48 at its lower end to the frame 22 and at its uplper'end carrying an antifriction roller 49 w ch is held constantly in the path of, or against, a cam 50 by the action of the before described gripper spring 43, the said cam 50 being fast to the cam shaft 8.

When the machine is at its stopping position the .movable knife 1 is at the top of its stroke, the feeler 28 at the left-most end of its stroke, and the ripper 41 is held away from the knife by t e cam 50; this being assumed to be the starting position, the operation ma be described as follows. W hen it is esired to compose a 2line letter matrix 12 into the, assembling line, the operator, b pressing back the lower ends 0 the two evers 36, 38, withdraws the rear ends of the two shelves 34, 37 from the channel of the assembler box 30 so as to leave.

room for said matrix to be inserted by the operator into the position in which its bottom rear lug 52 rests on the ordinary shelf 53, as indicated in Fig. 7 this position corresponding with that occupied by each of the. other or normal single line letter matrices 31 in the same com osed line, as shown best in Figs. 1 and 5. T e shelves 34, 37 are then returned to their respective effective positions in which their rear edges project into the channel of the assembler box 30, after which the operator proceeds to complete the composition of the line. The composed line is then passed into the first elevator (not represented in the drawings in connection with this arrangement of the apparatus) and the machine starts in the ordinary way. As the line is carried down to the front of the mold, themovable knife 1 is moved to its lowest position, and the feeler 28 is carried to its rightmost position clear of the composed line as it descends between the vise jaws 54, 55. The movable knife 1 is held down by the concentric part or dwell of the cam 19 until the mold is moved forward into contact with the composed line, at which juncture the said knife and the feelcr 28 are allowed to travel back until arrested by the said feelercngaging the nearest or righ t-most of the lugs 29 of the 2-line letter matrices 12.

If there is only one 2'line letter matrix in the composed line, and that situated at the end of the said line, the feeler will not reach it until the first justification has taken place,

With the ower,' and, as shown in Fig. 1 laterally deflected,

it in the position determined by the previous engagement of the feeler 28 with the appro The com osed line is priate matrix lug 29.

rst elevator next carried upwards by the during which movement the lug 29 of the special matrix 12 contiguous to the feeler 28, asses u against the left-hand side of such eeler, w rich latter however remains in. position owing to the movable knife -1 being then locked by the gripper 41. The composed line is then swept out ofthe first elevator, during which operation, the 2-.line letter matrices 12 (having no distributing teeth by which they can become attached to the second elevator) fall by gravity out of the assembler box ihto the front pibowl. The linotype is then ejected rom the mold slot 59,

which by that time b. been moved from the casting to the ejecting" position, and the 2 line letter of such linotype or the lowest of them passes immediately over the top of the position ready to start a fresh cycle ofoperations. When there are to be no 2-line letters on the linot pe, the operator pulls the rod 22 forward an thereby moves the cam lever 17 laterally 'out of the operative plane of the cam 19. To form the recess 56 on the next linotype as shown in Figs. 11 and 12, for receiving the over-hang of the 2-line letter or each of such 2line letters 57 of theirmnediately receding linotype, the o erator inserts the 2- ine letter matrix 12 wiichi was used for producing the said letter, in the same position as 'that which it occupied in the last preceding composed line, but when doing so he does not .withdraw the shelf 37 so that this matrix is supported by its lug 29 resting first on the shelf 87 and afterwards (when moved outwards through the assembler box) on the shelf 40 whereby the formative cavity 58 of that matrix 12 is maintained above the mold slot 59, Fig. 2, with the result that, during the casting operation, a blank 56 is formed, thelast named matrix lug 29, when thus supported, passes along what is known as the italic groove of the assembler. box.

75, Figs. 3 to 4' is the usual starting rod' crankcd near its front end to clear the movable knife 1.

Instead of the movable knife 1 bein lowered by the means hereinlwfore describe this operation may be effected by the mechanism represented in Figs. 13, 14 and stud 62 fast therein, working in a slot 63 in the web or panel 64 of the first elevator, the.

said stud 62 also preventing the sliding pin from rotating about its longitudinal axis. The sliding in pplsition, in w ich it is shown in dot-and-dash es near the -top of Fig. 13, is adapted during its descent, to engage with a stud 65 which is free to slide in vertical guides 66 on the vise frame 5. On this stud 65 is rota table a pulley 67 which engages in abight of a flexible cord or equivalent 68 of which, one end is attached to the vise frame 5 as for example by the hook 69, and the other end is attached to the movable knife 1, as for example by the bracket plate 70, Fig. 14, which is fixed to the upper end of the said knife. At intermediate parts of its length the cord 68 is guided by pulleys 7 1 rotatably mounted on any convenient supports or parts of the machine, the arrangement being such that when the first elevator 61 is lowered, the desired extent of downward travel shall also be imparted to the movable knife 1.

The vise frame 5 has attached to it two cams 72, 73, of which the .upper one 72, is adapted, by acting on the left-hand end of the slidable ,pin 60, to move .the latter into its right-most osition in which it is ca able of engaging with the stud 6.5, and the ower one 73, is adapted to move the said pin 60 left-ward out of engagement with the stud 65, by acting on a stud or projection 74 fast to the pin 60 and extending in a forward direction therefrom, this lower cam 73 being situated and shaped so as to effect the just mentioned disengagement when the stud has been depressed into its lowest position. The cam 72, though not so show'n-in the drawings, is preferably attached to the vise frame 5 so as to be capable of being moved into and out of its effective position in order that; when no 2-line matrices are being used, it shall have no effect upon the pin 60, which in turn, therefore will have. no effect upon the stud 65.

The action of the last described form of mechanism may be described as follows:" When the machine is in its stopping position, the first elevator 61 holds the slidable pin 60 in its topmost position, and the vertically sliding-stud 65 and the movable knife 1 are at the top of their respective strokes. Durin the descent of the first elevator 61, the sli%able pin 60 engages with, and dc resses the stud 65, and moves the movable ife 1 to its lowest position, in which position, by the before-described ipper 41, it is retained until the assembled line has been justified.

As the slidable pin 60 nears its lowest posi- 60, when in its right-most tion, the cam 73 moves it out of engagement with the stud 65 so that when the first elevator next ascends, the said pin 60 will clear the stud 65. As the first elevator ascends after the linotype has been cast, the upper-cam 72 moves the slidable pin 60 rightwards ready to engage the stud 65 at the next cycle of the machine.
